How to optimize consumer GPS systems within the electronic equipment

In addition, software-based GNSS another advantage, namely, the flexibility to support different GNSS technologies, such as the European Galileo is about to put (Galileo) system. Galileo system is operational on the U.S. Global Positioning System (GPS) supplement, made in any particular location will have more satellites, GNSS receivers to collect targeting signal. Can support both GPS and Galileo GNSS receivers in urban canyons can (urban canyon) to achieve higher positioning accuracy, and even a person in the end determine which side of the street walking. This improves the accuracy of the role of GNSS receivers, reliability, and most basic is to improve the user acceptance.

Because Galileo and GPS L1 frequency band of L1 using the same frequency band, so a receiver can use the same two systems, satellite tracking. If L1 and L2 frequency bands can be used to connect a dual-band receiver. However, because of the Galileo system and GPS baseband processor there are significant differences, only software-based approach not only substantial changes in the premise of the current GPS architecture to support the Galileo system. If you can upgrade the existing system through the software, which commenced operation in the Galileo system to provide immediate support services, which means to avoid costly delays in product development costs and seize opportunities.

GNSS software-based PC software modem will follow the pace of development is not through teaching people surprised. In the modem design, the PC has enough processing resources, engineers can save a
